Sermons and Secondary Literature
John Piper lets pastors know what it's important to study the Bible for themselves and carefully:
We must be like Jonathan Edwards, who resolved in his college days and kept the resolution all his life, “Resolved: To study the Scriptures so steadily, constantly, and frequently, as that I may find, and plainly perceive, myself to grow in the knowledge of the same.” Growing, advancing, increasing—that is the goal. And to advance we must be troubled by biblical affirmations.
It must bother us that James and Paul don’t seem to fit together. Only when we are troubled and bothered do we think hard. Paul told young pastor Timothy to think hard: “Think over what I say, for the Lord will give you understanding in everything” (2 Tim. 2:7). And if we don’t think hard about how biblical affirmations fit together, we will never penetrate to their common root and discover the beauty of unified divine truth—what David calls “wondrous things out of your law” (Ps. 119:18). The end result is that our Bible reading will become insipid, we will turn to fascinating “secondary literature,” our sermons will be the lame work of “second-handers,” and the people will go hungry.
